Spring break. Miyamura Miku, a hobby writer of light novels, is approached by her older sister Miyamura Karin, who reveals to her that she's working as a voice actress for erotic games. "The company I am working for right now needs someone to assist with writing the sex scenes!" Karin asks for Miku's assistance. "Wait, I'm still a virgin, you know? I have no clue how to write such a thing!" At the same time the protagonist, Shiiba Masashi, is getting a sudden call from his big sister. "Jeez, we can't! We're delaying. Can't. Impossible. We delay." The one who keeps repeating these phrases like a broken record, is the protagonist's older sister, Shiiba Sayaka - CEO as well as scenario writer of the popular upstart eroge brand "Hades Soft". "If we delay now, then we're done for. The sponsors will be chasing us for the rest of our life in order to reclaim the cash. We have to find a solution or I'll be to the neck in debt! I'll come haunt you if this kills me, okay?!" And so, Masashi ends up being roped into helping them with their eroge development?! This game is centering around eccentric heroines like the artist Suzumoto Chisa (pen name: Suzuse Akiko) and the reclusive colorist Sakakibara Ai. Here comes an ADV about creating eroge that's a little on the weirder side. IF YOU LOVE EROGE, DON'T JOIN AN EROGE COMPANY!
